A playoff incentive will be given to a team that will win five of their eight semifinal games should they fail to get the top two finals berths. The top two teams (or the No. 1 team and the winner of the playoff between team with at least 5 semifinal wins and the No. 2 team) will face each other in a best-of-seven championship series. In 1996, the league adopted a quarterfinal-semifinal playoff format with the top two seeds advancing automatically to the semifinals and the next four teams will be matched up in the quarterfinals after the eliminations. A different tournament format was used in 1998 when it carried over the elimination standings of the preceding Centennial Cup.
